<h3 id="downloading">Downloading</h3>

<p>Download package with latest release of the SOCI source code: <a href="https://sourceforge.net/projects/soci/files/soci/">soci-X.Y.Z</a>, where X.Y.Z is the version number. Unpack the archive.</p>

<p>You can always clone SOCI from the Git repository:</p>

<pre>git clone git://github.com/SOCI/soci.git</pre>

<h3 id="cmake">Building using CMake</h3>

<p>SOCI is configured to build using <a href="http://cmake.org/">CMake</a> system in version 2.8+.</p>

<p>The build configuration allows to control various aspects of compilation and installation by setting common CMake variables that change behaviour, describe system or control build (see <a href="http://cmake.org/cmake/help/documentation.html">CMake help</a>) as well as SOCI-specific variables described below. All these variables are available regardless of platform or compilation toolset used.</p>

<p>Running CMake from the command line allows to set variables in the CMake cache with the following syntax: <code>-DVARIABLE:TYPE=VALUE</code>. If you are new to CMake, you may find the tutorial <a href="http://cmake.org/cmake/help/runningcmake.html">Running CMake</a> helpful.</p>

<p>The following tables provide summary of variables accepted by CMake scripts configuring SOCI build. The lists consist of common variables for SOCI core and all backends as well as variables specific to SOCI backends and their direct dependencies.</p>

<p>By default, CMake will try to determine availability of all depdendencies automatically. If you are lucky, you will not need to specify any of the CMake variables explained above. However, if CMake reports some of the core or backend-specific dependencies as missing, you will need specify relevant variables to tell CMake where to look for the required components.</p>

<p>CMake configures SOCI build performing sequence of steps. Each
subsequent step is dependant on result of previous steps corresponding
with particular feature. First, CMake checks system platform and
compilation toolset. Next, CMake tries to find all external
dependencies. Then, depending on the results of the dependency check,
CMake determines SOCI backends which are possible to build. The
SOCI-specific variables described above provide users with basic
control of this behaviour.</p>

<h4 id="unix">Building using CMake on Unix</h4>

<p>Short version using GNU Make makefiles:</p>
<pre class="example">
$ mkdir build
$ cd build
$ cmake -G "Unix Makefiles" -DWITH_BOOST=OFF -DWITH_ORACLE=OFF (...) ../soci-X.Y.Z
$ make
$ make install
</pre>

<h4 id="windows">Building using CMake on Windows</h4>

<p>Short version using Visual Studio 2010 and MSBuild:</p>

<pre class="example">
C:\>MKDIR build
C:\>cd build
C:\build>cmake -G "Visual Studio 10" -DWITH_BOOST=OFF -DWITH_ORACLE=OFF (...) ..\soci-X.Y.Z
C:\build>msbuild.exe SOCI.sln
</pre>

<h3 id="unix-makefiles">Building using classic Makefiles on Unix (deprecated)</h3>

<p><em>NOTE: These Makefiles have not been maintained for long time.
The officially maintained build configuration is CMake. If you still want to 
use these Makefiles, you've been warned that you may need to patch them.</em></p>

<p>The classic set of Makefiles for Unix/Linux systems is provided for those users who need complete control over the whole process
and who can benefit from the basic scaffolding that they can extend on their own.
In this sense, the basic Makefiles are supposed to provide a minimal starting point for custom experimentation and are not intended to be a complete build/installation solution.<br />
At the same time, they are complete in the sense that they can compile the library with all test programs and for some users this level of support will be just fine.</p>

<p>The <code>core</code> directory of the library distribution contains
the <code>Makefile.basic</code> that can be used to compile the core part of
the library. Run <code>make -f Makefile.basic</code> or <code>make -f Makefile.basic shared</code> to get the static and shared versions, respectively.
Similarly, the <code>backends/<i>name</i></code> directory contains the
backend part for each supported backend with the appropriate <code>Makefile.basic</code>
and the <code>backends/<i>name</i>/test</code>
directory contains the test program for the given backend.</p>

<p>For example, the simplest way to compile the static version of the
library and the test program for PostgreSQL is:</p>

<pre class="example">
$ cd src/core
$ make -f Makefile.basic
$ cd ../backends/postgresql
$ make -f Makefile.basic
$ cd test
$ make -f Makefile.basic
</pre>

<div class="note">
<p><span class="note">Note:</span>
For each backend and its test program, the <code>Makefile.basic</code>s
contain the variables that can have values specific to the given
environment - they usually name the include and library paths.
These variables are placed at the beginning of the <code>Makefile.basic</code>s.
Please review their values in case of any compilation problems.</p>
</div>

<p>The Makefiles for test programs can be a good starting point to find out correct compiler and linker options.</p>

<h3 id="testing">Running regression tests</h3>

<p>The process of running regression tests highly depends on user's environment and build configuration, so it may be quite involving process. The CMake configuration provides variables to allow users willing to run the tests to configure build and specify database connection parameters (see the tables above for variable names).</p>

<p>In order to run regression tests, configure and build desired SOCI backends and prepare working database instances for them.</p>

<p>While configuring build with CMake, specify <code>SOCI_TESTS=ON</code> to enable building regression tests. Also, specify <code>SOCI_{backend name}_TEST_CONNSTR</code> variables to tell the tests runner how to connect with your test databases.</p>

<p>Dedicated <code>make test</code> target can be used to execute regression tests on build completion:</p>
<pre class="example">
$ mkdir build
$ cd build
$ cmake -G "Unix Makefiles" -DWITH_BOOST=OFF \
   -DSOCI_TESTS=ON \
   -DSOCI_EMPTY_TEST_CONNSTR="dummy connection" \
   -DSOCI_SQLITE3_TEST_CONNSTR="test.db" \
   (...)
   ../soci-X.Y.Z
$ make
$ make test
$ make install
</pre>

<p>In the example above, regression tests for the sample Empty backend and SQLite 3 backend are configured for execution by <code>make test</code> target.</p>

<h3 id="usage">Libraries usage</h3>

<p>CMake build produces set of shared and static libraries for SOCI core and backends separately. On Unix, for example, <code>build/lib</code> directory
will consist of the static libraries named like <code>libsoci_core.a</code>, <code>libsoci_sqlite3.a</code> and shared libraries with names like
<code>libsoci_core.so.3.2.2</code>, <code>libsoci_sqlite3.so.3.2.2</code>, and so on.</p>

<p>In order to use SOCI in your program, you need to specify your project build configuration with paths to SOCI headers and libraries,
and specify linker to link against the libraries you want to use in your program.</p>
